Abstract

PURPOSE:To perform machining with high accuracy, by always accurately maintaining the degree of parallelism of a cross rail to the top of a table even if the cross rail is repeatedly moved up and down. CONSTITUTION:When a cross rail 6 is repeatedly moved up and down, the degree of parallelism of the cross rail to a table 2 falls. The fall is detected in terms of the difference between two values shown on an indication unit 36 and corresponding to the levels of the right and left ends of the cross rail 6. The end of the cross rail 6 having deviated down as to the top of the table 2 is lifted by an adjuster 37 or 38 in response to the detection of the fall so that both the indicated values coincide with each other. The cross rail 6 is thus kept parallel with the top of the table 2. This leads to plane machining with very high accuracy of micron order.
